`Application 1ed.-8eptember 2951827." SeriallNo. 2224,77mn

\ The subject'fmatterlof: tliefprersent invern-` tion relates generally to nnproveinents in roof constructions for glazedbuildings; such` as greenhouses or; conservatories and. the like;y x .H i

@ne of the features of the-invention re sides in the provision of meansfor supportingk the sash-bars,"` Whiclrin turn carry. the covering elements of-the roof.l r

In one oft the examples. of thefifvention illustratively presented .in ther drawings there is shown a saeh'bar,channeL-like in cross-section, the same being constructed-:of relatively thinmaterialilso that the sides of said bar may flex and accommodate the lateral movements of the covering elements. It is therefore essential that the means for supporting the sash-bars themselves shall possess the faculty of accommodating the longitudinal movements Vof the same and at the same time permit the lateral movements of said sash-bars.

To this end my `improved supporting tions secured to certain of the structural elements of the roof, the stringers, forinstance, and having the channeLlike sash-bars rockably engaged by the bight portions of the supporting means, fora purpose to be presently pointed out.

In the accompanying drawing, a practical example of the invention is shown, wherein: i

Figure 1 is a sectional detail ofa portion of the roof structure embodying the invention.

Figure 2 is a transverse sectional view taken on the line 2-2 of Figure l, the same.`

being slightly enlarged.

Figure 3 is a sectional view taken .substantially on the plane of the line 3-3 of Figure 2, to illustrate the means for connecting the sash-bars to the tops or bight portions of the supporting means; and

Figure 4;' is a view like unto Figure 2 but illustrating a slight change in form.

Referring now more specifically to the accompanying drawing, wherein like characters of reference denote similar parts throughout the several views, let 5 denote the rafters of a roof structure, the same beingV connected by a plurality of transverse stringers 6 and bridging the spaces therebetween. y V

Positioned abolveisaid rafters and disposed paralletly therewithgiare aiplurality of chan# nelJikeisaslnbars 7 the same having lateral flanges.- 8 to I supporti the covering elements 9 ofthe structure.` The means for supporting said sashbars 7 comprises 'the4 members `10, substantially invertedmU-shaped inf cross-section and presenting elongated leg: portions 11 having their "extremities abutting: eachv of the stringere:1 6i andi'securedi` to the lowery leg thereof by means ofthe fastening` means12` and angliedronsl,` as: clearly shown` in` Fig-i ure 2.a AThea uppert end orfbight portion 114 of each of said members 10 is formed to seat Within the upper portion of said sash-bars 75 and is secured thereto by means of bolts 17, passing through apertures 18. Thus longi tudinal movements of the sash-bars are accommodated by a slight rocking on said members 10. However, under some conditions the lateral deflection of said sash-bars is somewhat pronounced, due to the expansion of the covering elements 9, and this condition being greater adjacent the area contactedby said elements 9, I propose to bow inwardly the leg portions 11 of said members 10, as indicated at 15, and thus the movements of the sash-bars are accommodated. Any abnormal expansion of the Vcovering elements and attendant deflection of the saslnbars may be compensated in view of the resiliency of said members 10.

In the form shown in Figure 4, the bight portion 14 of said members 1() engages the inner portion of said sash-bars 7, yet the engagement is not snug enough to prevent movements between the parts when said sashbar expands or contracts longitudinally.

From the foregoing it is apparent that I have developed a structure exceedingly simple in construction, yet possessing sufficientr rigidity to withstand the weight of the covering elements, and having inherent resilient qualities to accommodate the movepents of both covering elements and sashars.

While the disclosure covers the preferred embodiment of the invention, it is to be understoodthat minor changes and alterations may be resorted to liberally without departing from the spirit of the invention as defined in the appended claims.

with the framework including stringers and covering elements, resilient channel-like sashbars for supporting said covering elements and adapted to absorb the expansion of said elements, and' resilient channel-like mean for supporting said sash-bars.

2. ln a roof construction, in combination With stringers and covering elements, resilient channel-like sash-bars for. supporting said covering elements, and resilient means substantially inverted U-shaped in crosssection connected to said stringers and supporting said sash-bars, said means presentmg bowed portions to accommodate the lateral flexing of said sash-bars.

3. In a roof construction, in combination with stringers and covering elements, resilient channeldike sash-bars for supporting said covering elements and channel members for supporting said sash-bars, said members being substantially inverted U-shaped in cross-section, the bight portion thereof loosely abutting said sash-bars andV the leg portions being rigidly connected to said stringers, and said leg portions being bowed adjacent the lower portibns of said sashbars to accommodate the lateral movements thereof. y Y
